External directories
Directory links are for discovery and citation. Their presence here is not a blanket license to copy or host material from those sites.
Access is not permission.
Finding a PDF online does not by itself authorize republishing it. Rights depend on the specific edition, translation, annotations, scan, cover, and the terms that apply to each item.
Edition-level review
Public hosting requires evidence for the exact edition and its distribution basis. A work’s age alone does not establish the rights status of a modern edition or scan.
Clear cover labels
Catalogue artwork is a design aid, not a facsimile. Scanned covers should link to their source and show creator and license details when recorded.
Help us review a specific record.
Open the relevant public book page and use its “Report a rights concern” form. Include enough detail to identify the source or edition; a curator can then review the evidence and decide whether access should change.
Rights labels on older catalogue records have not all been independently verified. A public listing is not a legal guarantee. This operational summary is not legal advice.
